Biology

Glalie is a spherical Pokémon that consists of a black rock core covered by ice. The icy covering has several holes and spaces across this Pokémon’s body. Blue eyes and a mouth with flat teeth are visible through three of these holes. There are two large, black, conical horns on either side of Glalie's head. Its icy body will not melt, and it can control ice by freezing moisture in the air. This ability is used to freeze its opponents, which it then consumes. It can be found in caves.

Mega Glalie's mouth extends to the length of its face. The lower jaw is all black except for two light-blue, conical, icy spikes. The pupils in Mega Glalie's eyes are now red instead of black. The horns on top Mega Glalie's head have been partially turned into ice, with the addition of a third horn on its forehead.

In the manga

In the Pokémon Adventures manga

Noland is seen picking a Glalie as one of his rental Pokémon in his battle against Emerald. Although it came close to winning by delivering a would-be-fatal Sheer Cold that succeeded in hitting its target, Emerald's Sceptile was in fact, unbeknownst to both Noland and Emerald, not meant to be a rental Pokémon and survived due to its higher level. It eventually lost to Sceptile's Iron Tail, allowing Emerald to win the Knowledge Symbol.

Trivia

Origin

Similar to Jynx, Glalie is based on human features, most likely on a cold, distant person or facial expression. It also looks somewhat similar to an ice hockey mask. Due to its horns and teeth, it may be based on a standard oni or possibly even onigiri, as its Japanese name suggests. It also resembles a hailstone.
